Opinion by
Mr. Justice Pomeroy,Early on the morning of May 23,1970, three persons died in a fire which gutted a residence at 40 East Silver Street, Philadelphia. Appellant Joseph Ewell was arrested later that morning and charged with starting the *591fire. That afternoon, Ewell gave a statement to the police admitting responsibility for the blaze. A motion to suppress this statement was denied after a hearing on the issue of its voluntariness, and the statement, along with the corroborating testimony of several witnesses, was introduced at his trial. Appellant was convicted on three counts of first degree murder and one count of arson, and, after denial of post-trial motions, was sentenced to life imprisonment. An appeal to this Court followed.1
We will consider first appellant’s contention that his motion to suppress his confession was improperly denied. When a defendant alleges that his confession was coerced, the burden is on the Commonwealth to prove the voluntariness of the statement by a preponderance of the evidence. Commonwealth ex rel. Butler v. Rundle, 429 Pa. 141, 239 A.2d 426 (1968). Where the hearing judge has found that a statement was voluntarily given, “our review is limited to a consideration of the testimony of the witnesses offered by the Commonwealth and that portion of the testimony for the appellant which remains uncontradicted”. Common*592wealth v. Davenport, 449 Pa. 263, 267, 295 A.2d 596 (1972); Commonwealth ex rel. Joyner v. Brierley, 429 Pa. 156, 239 A.2d 434 (1968).
Appellant did not testify at the suppression hearing, nor did he present any witnesses in his behalf. The Commonwealth called as witnesses four detectives who had taken part in Ewell’s arrest and interrogation. The gist of their testimony was that Ewell was arrested at about 11:15 a.m. on May 23, 1970, the morning of the fire. The arresting officers informed Ewell that the charge was homicide. He was taken promptly to the police station, where he was given the required constitutional warnings by a detective Cleary. Ewell appeared to be normal and not under the influence of alcohol or drugs, and his answers indicated a clear understanding and waiver of his rights to silence and the assistance of counsel. A chronology compiled by Detective Cleary and offered in evidence shows that Ewell was given food, coffee and cigarettes an hour or so after the interrogation began, and received additional cigarettes and water thereafter. Ewell admitted his responsibility for the fire at about 2:20 p.m. After making three telephone calls, using the men’s room, and resting and smoking for a while, he dictated, read and signed the formal statement which was introduced at his trial. The credibility of the Commonwealth’s witnesses was a question for the hearing judge. On the record before us, the Judge was fully warranted in finding that the confession was voluntary.
The other points raised by appellant all concern the court’s charge to the jury. We will limit our consideration to the one point which requires a new trial. In his discussion of appellant’s confession, the trial judge instructed the jury that “... the burden of proving that the defendant’s statement was voluntary and true rests upon the Commonwealth and that burden must be sustained by a preponderance of the evidence” [emphasis *593supplied]. While this is a correct statement of the law on the question of voluntariness,2 it is, of course, not correct with regard to the truth of appellant’s statement. The Commonwealth need not prove every specific evidentiary fact in its case in chief beyond a reasonable doubt; this burden attaches only to the elements of the crime charged.3 A defendant’s voluntary out-of-court statement is merely another piece of evidence to be considered in resolving the ultimate issue of guilt or innocence, and jurors can attach as much or as little weight to it as they see fit. In the case at bar, the jury might have disregarded Ewell’s statement altogether and still have convicted him on the other evidence introduced by the Commonwealth. The difficulty here, however, is that the converse is also true; the statement constituted an admission of every fact necessary to establish appellant’s guilt. Since the facts constituting the corpus delicti were undisputed, the confession was in itself a sufficient legal basis for Ewell’s conviction. Indeed, the trial judge so instructed the jury when he said, soon after giving the erroneous instruction previously quoted: “Summing up on this issue, therefore, you can find the defendant guilty of felony-murder, if you find this statement which he gave to the police of his participation in the arson was voluntarily given and that it was true; however, if you find his statement was not voluntarily given or that it was not true, then you cannot consider that statement as any evidence of the defendant’s guilt and you must then determine from other evidence whether the defendant’s guilt of arson and murder has been established. . . (Emphasis supplied.) We think that, taken together, the passages we *594have quoted from the charge permitted the jury to return a verdict of guilty on the basis of a preponderance of the evidence, even if the jurors entertained a reasonable doubt as to appellant’s guilt.
It is, of course, a well-settled rule of law that the charge to the jury must be considered as a whole. Commonwealth v. Fostar, 445 Pa. 216, 317 A.2d 188 (1974). In the case at bar, the court told the jury that “[y]ou should consider the facts and circumstances surrounding the making of a statement, along with all other evidence in the case in judging its truthfulness and deciding how much weight, if any, the statement deserves on the question of guilt or innocence”. In addition, the court several times charged the jury that the burden was on the Commonwealth to prove the defendant’s guilt beyond a reasonable doubt. Nevertheless, on a matter as important as the Commonwealth’s burden in a criminal case to prove all elements of the crime beyond a reasonable doubt, we cannot say that the error was cured by these other portions of the charge which correctly stated the general rule. A similar mistake was made in the charge to the jury in Commonwealth v. Ross, 266 Pa. 580, 583, 110 A. 327 (1920), where the trial court placed too high a burden of proof on the defendant in his attempt to establish the defense of self-defense. In that case, the court told the jury that “[w]here the defense is self-defense, it is not enough to present evidence under which the jury may doubt whether or not the defendant may have acted in self-defense. When any doubt on that subject exists, self-defense is not established. But when established by a fair preponderance of the evidence, it is excusable homicide.” (Emphasis supplied.) Reviewing this instruction, this Court said: “That [italicized portion of the] statement was equivalent to saying that self-defense must be established beyond a reasonable doubt, which is incorrect, for it ignores the distinction between fairly pre*595ponderating evidence and that which is beyond a reasonable doubt. We know, as lawyers, that the trial judge had no such thought in mind — in fact, he repeatedly stated the law to the jury upon this branch of the case with entire accuracy; but we cannot know judicially that the accidental misstatement did defendant no harm. It is enough that the jury may have received thereby a wrong impression as to the quantum of proof necessary to establish self-defense.” 266 Pa. at 583. (Emphasis supplied.) The underlying rationale of the Boss case and kindred decisions4 is controlling here.
The Commonwealth argues that the error in the charge was harmless because the corroborative evidence introduced by the Commonwealth was so overwhelming. We cannot accept this argument, for we may not speculate as to the basis of the jury’s verdict. Strong as the Commonwealth’s case was, the jury was nonetheless free to reject it in its entirety and instead accept the alibi defense which Ewell tendered; it is conceivable that, absent the error in the charge, they might have done so. Moreover, under the instructions given by the court, a juror might have concluded that if he found Ewell’s statement credibile on its face, he was relieved of any obligation to consider the other evidence offered by the Commonwealth. It is not for us to say what in fact happened in the jury room, or what would have happened if the jury had been correctly instructed.
It is true, as the Commonwealth points out, that no specific objection was taken to the instruction now challenged. We do not agree, however, that appellant has thereby waived this point.5 The United States Su*596preme Court has recently placed renewed emphasis on the reasonable doubt standard by holding it to be an essential element of constitutional due process in a criminal proceeding. In re Winship, 397 U.S. 358, 25 L.Ed.2d 368, 90 S. Ct. 1068 (1970). The instruction challenged in the case at bar was more than just a “tangential undercutting” of this standard, such as was found in Cupp v. Naughten, 414 U.S. 141, 38 L.Ed.2d 368, 375 [94 S. Ct. 396, 401] (1973); it set up an entirely different criterion for determining guilt or innocence. We held in Commonwealth v. Williams, 432 Pa. 557, 248 A.2d 301 (1968) that an instruction which permitted a jury to find a defendant guilty when the jurors were not so convinced beyond a reasonable doubt was reversible error even in the absence of a specific exception to the charge. This is just such a case.6 See also Commonwealth v. Noble, 371 Pa. 138, 142-144, 88 A.2d 760 (1952).
This is not a case in which appellant’s failure to bring the error in the charge to the attention of the lower court was in any way deliberate. Defense counsel was assiduous in taking exception to a number of such alleged errors, and, in addition, submitted a correct point for charge on the evidentiary weight to be given a voluntary confession.7 The failure to note this *597particular error was as inadvertent as the trial judge’s initial slip of the tongue. But we cannot sustain this verdict on the mere speculation that the jury was equally inattentive.
The judgment of sentence is reversed, and the case is remanded to the court below for a new trial.
Mr. Justice Nix concurs in the result. Mr. Chief Justice Jones dissents.Appellant’s arson conviction resulted in a sentence of imprisonment for not less than ten nor more than twenty years, to run concurrently with the three concurrent sentences of life imprisonment imposed on the murder counts. Under the Appellate Court Jurisdiction Act, appellate jurisdiction of Ewell’s arson conviction is vested in the Superior Court. Act of July 31, 1970, P.L. 673, No. 223, Art. III, §302, 17 P.S. §211.302. The Commonwealth has not interposed an objection on this score, however, and the failure to object operates to perfect this Court’s jurisdiction of the arson appeal unless the Court orders otherwise. Appellate Court Jurisdiction Act, supra, §503, 17 P.S. §211.503. While ordinarily we would transfer an arson appeal to the Superior Court, such a course is obviously inappropriate where we have exclusive appellate jurisdiction of appellant’s felony-murder convictions arising out of the same facts and involving the same questions of law as does the arson charge. Compare Commonwealth v. Rife, 454 Pa. 506, 508 n.1, 312 A.2d 406 (1973).

This issue was raised below in argument before the court en banc, cf. Commonwealth v. Carbonetto, 455 Pa. 93, 314 A.2d 304 (1974), Commonwealth v. Dancer, 452 Pa. 221, 305 A.2d 364 (1973).
Pa. R. Crim. P. 1119(b), wbicb became effective shortly after we heard argument in Williams, does not foreclose our consideration of this issue in the case at bar. Commonwealth v. Jennings, 442 Pa. 18, 274 A.2d 767 (1971).
The submitted point for charge reads as follows: “If you decide that the defendant knowingly, intelligently and voluntarily gave the police a confession you must next decide what, if any, effect the words or statement in question should be given in this ease. Then, the usual means of determining truth, falsity and believability, as I have already instructed you, should be applied to the content of the confession.” The trial judge refused this point on the ground that it had already been covered in his instructions to the jury. Appellant suggests that the submission of this point for charge *597preserved an exception to the instruction actually given. This point was not, however, specifically addressed to the applicable evidentiary standard, and we doubt that its refusal was sufficient in itself to relieve counsel from the obligation to take a specific exception to the charge. Cf. Commonwealth v. Sisak, 436 Pa. 262, 269, 270, 259 A.2d 428 (1969).
